Spray dryer
FILTERMAT™
GEA Niro
GEA Niro's range of spray dryers are designed to handle all types of products generally available in powder form. However, with higher carbohydrate and fat content the spray drying process becomes more difficult, and the limiting factor becomes powder deposits in the drying chamber, air ducts with powder loaded air and cyclones.
GEA Niro has, therefore, designed a FILTERMAT™ spray dryer that will dry products, which cannot be dried in any other type of spray dryer.
The FILTERMAT™ process
The FILTERMAT™ spray dryer is based on co-current nozzle atomization, where the nozzles are placed right below a specially designed air disperser with two air inlets. The air flow ensures that the atomized product particles do not get in contact with the chamber wall.
Should it, however, happen then the air cooled chamber surface prevents scorching to the deposits. The product particles with high moisture content will fall onto the bottom of the drying chamber, which is formed as a moving belt.
